What is the effect of presenting fabricated evidence on a suspect who has agreed to talk?

• A. It guarantees admissibility of any resulting confession
• B. It can persuade a suspect to admit by creating belief in wrongdoing
• C. It always leads to false confessions
• D. It is never used in formal proceedings

Answer: (B)

Presenting fabricated evidence to a suspect who has agreed to talk can persuade them to admit wrongdoing by creating the belief that investigators already have proof. The pressure to end the interrogation and to appear cooperative leads the person to concede in order to stop the questioning, align with what they think the investigators believe, and reduce uncertainty. This drives an admission even when the evidence doesn’t exist, highlighting how perceived proof can shape confession behavior. It’s not a guarantee that any confession will be admissible, and while it raises the risk of false confessions, it doesn’t mean all such admissions are false. The tactic is controversial and not unheard of in formal proceedings, though it faces strong ethical and legal scrutiny regarding voluntariness and reliability.
